Abstract
The utility model discloses a core bag structure of an aluminium electrolytic capacitor; the core bag structure comprises an anode aluminium foil, a cathode aluminium foil, an anode guide line, a cathode guide line and at least three layers of electrolytic papers positioned between the anode aluminium foil and the cathode aluminium foil; fixed tongue portions of the anode guide line and the cathode guide line are respectively welded to corresponding anode aluminium foil and cathode aluminium foil; the fixed tongue portion of the anode guide line is positioned on one side of the anode aluminium foil departing from the electrolytic paper; and the fixed tongue portion of the cathode guide line is positioned on one side of the cathode aluminium foil departing from the electrolytic paper. Compared with a riveting mode, the welding mode will not generate burr phenomenon, thereby preventing the electrolytic paper from being penetrated and solving the disadvantages of capacitor short circuit breakdown and even explosion caused by the burrs; furthermore, the electrolytic paper layer formed by stacking at least three layers of electrolytic papers can ensure a sufficient thickness, so protrusion positions generated in welding can hardly penetrate the electrolytic paper layer; and the anode guide line and the cathode guide line are respectively arranged departing from the electrolytic paper. The core bag structure of the aluminium electrolytic capacitor is stable in structure and long in service life.
